Posted on April 14th, 2010 51 commentsWho else in the industry can give you 52 solid minutes of beginner advice on buying a multimeter?
Dave of course!, who started out wanting to give some “quick” advice, but as usual Dave likes to rant…

EEVblog #67 – Hacking the Princeton Tec EOS LED Headlamp with a Cree XPG
Posted on March 10th, 2010 42 commentsDave does a teardown of the Princeton Tec EOS headlamp and mods it with a new Cree XPG LED.
Throw in a quick reverse engineer of the circuit, gratuitous scope shots, torturing a thermistor, a practical demonstration of why you really do need 5 multimeters on your bench, and as usual Dave finds no problems filling up 25 minutes.
